I was just trying to understand JohnD's argument. But this seems to clear it up.
AI Overview
While it is true that Arabic is a Semitic language and Arabs are linguistically and historically considered a Semitic people, the term "anti-semitic" is not applied to anti-Arab racism due to its specific historical origin and colloquial usage.
As I've said previously, anti-Jew has a special terminology all to itself. It's adopted the term anti-Semitism, even though it is scientifically incorrect.
But the conflation of anti-Israel and anti-Zionism with anti-Semtisim is also scientifically incorrect, but many still try to conflate the terms.
In reality, it means when Israelis, Jews, Zionists or their supporters are complaining about discrimination, they are limiting their complaints to anti-Jew, anti-Semitism hostility. They appear to have no concern for all the other types of discrimination in the world, only theirs. And often practise their own form of racial hostility, even Apartheid, e.g anti Muslim, anti-Palestinian, etc.
Whereas other activists encompass all types of racial, sex, gender, age, disability, etc hatred and discrimination.
